The Tecnosky Variable Flattener 1.0x Full Frame is designed to provide edge-to-edge sharpness for full-frame astrophotography when used with a range of Tecnosky apochromatic refractor telescopes. This flattener is compatible with models featuring apertures of 80, 90, 102, 115, 130, and 152 mm, making it a versatile choice for many setups. With standard M63 and M48x0.75 connections, it integrates easily with most telescopes and cameras. The 55 mm backfocus and built-in filter thread ensure convenient and flexible use for demanding imaging applications.

The Tecnosky Variable Flattener 1.0x M48 is an optical accessory designed to correct the natural field curvature produced by refractor telescopes. Without a flattener, stars at the edge of the image may appear distorted or less sharp compared to those in the center. By installing this field flattener between the telescope and the camera, astrophotographers can achieve sharp, pinpoint stars across the entire image, resulting in higher-quality astrophotography. This accessory is particularly useful for refractors with focal lengths between 400 mm and 1000 mm.

The Tecnosky Adjustable Flattener Reducer FF 0.8x is an optical accessory designed to improve astrophotography by correcting the natural field curvature produced by telescope optics. Without a flattener, stars near the edge of the image may appear distorted or blurry, reducing overall image quality. By installing this field flattener between your telescope and camera, you can achieve sharp, pinpoint stars across the entire field, even at the edges.

The Tecnosky Off-Axis-Guider Deluxe offers a simple and efficient way to guide your telescope during astrophotography sessions. Instead of mounting a bulky guide scope, this compact and lightweight device allows you to track stars accurately, making it especially suitable for smaller telescopes and mounts that cannot handle much extra weight. By deflecting a small portion of incoming light with a lateral prism, the off-axis guider enables precise tracking through a reticle eyepiece or auto guider, while your main camera continues to capture the image.
